2. Every organism in this earth is surrounded by a lot of things; say other organisms, plants, water, air, light, land etc. These surroundings of the organism, all the living and non-living things constitute its environment Definition: Environment is a combination of various physical and biologycal elements that affect the life of an organism Introduction

3. Components Of Environment

4. Physical C omponents of Environment The Physical C omponents of environment includes soil , water , air, climate, temperature , light etc. P hysical C omponents of the environment is again divided into three parts. These are:

5. Atmosphere A layer of gases S urrounding a  planet O ther   material body  of sufficient  mass T hat is held in place by the  gravity  of the body

6. Atmosphere

7. Major layers of the Atmosphere

8. Atmospheric Composition

9. Hydrosphere It includes the surface water and its surrounding interface Water is the most abundant substance on the Earth’s surface. The oceans cover approximately 71% water of the planet, glaciers and ice caps cover additional areas. Water is also found in lakes and streams, in soils and underground reservoirs, in the atmosphere, and in the bodies of all living organism. Thus, water in all its forms- ice, liquid, water and water vapor- is very familiar to us.

10. Hydrological Cycle

11. Lithosphere It is the outer boundary layer of solid earth and the discontinuity within the mantle . Basically lithosphere is nothing but a crustal system composed of various layers: Core, mantle and outer crust.

13. Biological component s of Environment There are two kind of Biologycal components. They are

14. The Abiotic components of Environment   A biotic components  are non-living c hemical  and p hysical  factors in the  environment . Abiotic phenomena underlie all of biology. Abiotic factors, while generally downplayed, can have enormous impact on  evolution . Abiotic components are aspects of geodiversity . They can also be recognised as " abiotic pathogens“ E.g- Temperature, light, sun light, pH, soil components, etc.

15. The biotic Components of Environment This component consists of all living things like plants, animals and small micro-organisms like bacteria. All ecosystems consist of three different types of living organisms. Biotic Component Producer Consumer Decomposer

16. Producers G enerally green plants and other photosynthetic bacteria P rod uces various o rganic substances W ith the help of water, soil and light energy. E.g. Plants

17. Consumer Consumers depend for their nutrition on the organic food produced by the green plants, E.g animals.

18. Decomposers B ring about the decomposition of dead plants and animals R eturn various important minerals F or the running of the biogeochemical cycles E .g. fungi and bacteria.

19. Cultural Environment The Cultural Environment gives an idea of learned behavioral traits those are clear and shared by members of society The most important thing about the cultural environment is that it cannot be physically represented, but it is there anyway.
